Chapter 175 Extreme High Imitation (Guaranteed 1, please subscribe)

Although he didn't think it was genuine, he couldn't stand Wu Er's urging.

Chen Wenzhe put on his gloves, and carefully took the things out of the gift box.

This is really a heavy weapon, holding it in your hand is very overwhelming.

This blue and white plum bottle with cloud and dragon pattern is 41.6cm high, 6cm in diameter and 14cm in foot diameter.

The plum vase has a folded edge, a thin neck, full shoulders, the shoulders are gradually convergent, and the feet are circled.

Plantar unglazed, flint red.

From top to bottom, the outer wall is divided into five layers with blue and white double string lines.

The shoulders are painted with curly grass patterns and drooping cloud shoulder patterns, the cloud shoulders are painted with twining chrysanthemum patterns, and the cloud shoulder patterns are decorated with curly grass patterns.

The abdomen is painted with cloud and dragon patterns, and the shins (jìng sound diameter) are painted with curly grass patterns and Yanglian petal patterns.

It can be said that there are everything that should be on the Yuan blue and white, but this is just the appearance.

The counterfeiting of Yuan blue and white porcelain began in the Republic of China, because at that time, no one in China believed that blue and white porcelain existed in the Yuan Dynasty, and they all thought it was something after the Ming and Qing Dynasties.

Therefore, no one imitated it before, because the Chinese people did not know the existence of Yuan blue and white.

Isn't it ironic that this thing was discovered by foreigners?

Jingzhen’s porcelain began to be inscribed in Yongle in the Ming Dynasty, so the Ming and Qing porcelains after Yongle are very easy to confirm.

In the Yuan Dynasty before the Ming Dynasty, due to the short period of rule, it was not enough to form its own characteristics, and there was no inscription, so there was a lack of convincing objects to demonstrate the porcelain of this period.

It was not until an Englishman named Pope [-] or [-] years ago, after comparing the porcelains in Turkey and the promise museum, that he came to the conclusion of Yuan blue and white porcelain and published it.

And the object of this main demonstration is the "Elephant Ear Vase with Inscribed Blue and White Cloud and Dragon Pattern".

Like this one, it also has a cloud and dragon pattern, and there is also a blue and white plum vase with a cloud and dragon pattern in the Palace Museum.

This one is likely to be imitated based on that one.

Others, Chen Wenzhe doesn't know, he is a professional to check the device type by feel.

This blue and white plum vase is very delicate in workmanship, the cloud and dragon patterns are depicted, and the image is quite vivid, but the shape of the vessel is not beautiful, especially the center of gravity is a bit tilted.

This is entirely due to the unqualified embryo-making process. This plum vase is more than [-] centimeters high.

The embryos of the utensils are not good enough to reach the level of a master. This is obviously different from the workmanship, blue and white and cloud dragon patterns on the outside.

This kind of situation was impossible in ancient times. How could the master who fired such a tall and heavy vessel be an ordinary person?

That's why Chen Wenzhe didn't want to touch Yuan Qinghua. If it wasn't for his super strong hand feel, how could he see some defects in the internal embryo?
Just take a look at the blue and white, workmanship and cloud dragon pattern on the outside, and you will generally surrender.

If you don't have a certain level, you should be running around in your heart at this time, thinking that you have encountered a national treasure.

Many people now know what the external blue and white painting and techniques of Yuan blue and white look like. It can be said that various characteristics have been popularized.

For example, the curly grass pattern or the edge of the cloud head pattern, as well as the wishful cloud head pattern and the banana leaf pattern, but these things are all visible and can be imitated.

It cannot be imitated, or what cannot be imitated is the fetus. This is also an important reason why many counterfeit antiques are played at the bottom.

The quality of the Yuan blue and white porcelain is not as fine as that of the Ming and Qing porcelains, so there are many trachoma, brush marks and iron spots on the sand bottom, and flint red on the bottom feet, mouth edges and shrinking glaze exposed tires.

In addition, the utensils of the Yuan Dynasty were made of hemp warehouse soil. After aging, trachoma is likely to appear on the bottom of the utensils.

Therefore, the real Yuan blue and white bottom tire looks very rough, but it feels very delicate when touched by hand, which is a typical characteristic of Ma Cang soil.

By this time, Chen Wenzhe had almost figured out the routine of this Yuan blue and white piece.

This piece of porcelain seems to be a master craftsman except for the tire.

You must know that the current Ma Cang soil has disappeared, and without Ma Cang soil, it is impossible to imitate Yuan blue and white flowers.

If Chen Wenzhe guessed correctly, the inner tube of this porcelain should be a plum vase made of Macang soil.

It is definitely not from the Yuan Dynasty, it is likely to be from the Ming Dynasty. You must know that before Wanli in the Ming Dynasty, there was still Ma Cangtu.

That's right, the unknown counterfeiter used a Ming Dynasty embryo, refired it in the kiln, and made a high-quality imitation of such a Yuan blue and white piece.

His porcelain making skills should be very good, but he has no choice but to use such a slightly flawed old tire.

Such a high imitation of a piece of Yuan blue and white can easily deceive the masters in the industry.

Chen Wenzhe glanced at Wu Er, really wondering where he got this thing.

At this point, Chen Wenzhe became more serious.

In addition to looking at the tire, it is to look at the glaze. There must be a difference between modern cobalt materials and Yuan Dynasty cobalt materials.

In fact, the imitations that have had a greater impact on the collection industry are the imitations that have appeared in the past ten years.

Now the level of craftsmanship is much higher than in the past, and the information is more developed. The imitators can easily get in touch with the real products through various channels.

Such conditions are better than those in the Guangxu, Xuantong, and Republic of China periods of the Qing Dynasty.

However, the green materials used in painting are basically chemical green materials, that is, the chemical cobalt oxide.

In theory, relatively pure chemical green materials can be used to prepare any blue and white hair color, but in practice, it is extremely difficult to do so.

Cobalt oxide is black-gray powder, light gray-green powder, or pink powder. The color of the prepared pigment is not equal to the color of blue and white after firing at a high temperature of 1300 degrees.

It is extremely difficult to deduce the cause (the ratio of cobalt oxide raw materials) from the result (blue and white color), and requires a lot of process exploration.

The coloring effect of cobalt oxide is relatively strong. One of the reasons why the imitation Yuan blue and white is popular is that the color of Yuan blue and white is also relatively strong, and it is easy to get away with it.

Many collectors hide when they see Yuan blue and white, which must be related to this.

After all, chemical green materials are very different from natural Sumaliqing.

Chemical green materials are relatively pure, but Sumaliqing contains a lot of impurities. It is definitely not easy to use chemical green materials to prepare Sumaliqing.

In this way, if high imitators want to be comprehensive, they will spend a lot of money.

They are here to make money, not to pursue art, so even if they know that many details may be seen through, they still won't do them.

For example, this Yuan blue and white piece has two main flaws, one is that the shape of the vessel is not regular, and the other is the blue and white material that imitates Su Maliqing.

As for the hemp warehouse soil exposed from the bottom tire, it is true, and no one can find the problem.

In fact, the two most important things in appraising Yuan blue and white are Su Maliqing and Ma Cangtu. As long as these two conditions are met, everything else is trivial.

Through this Yuan blue and white piece, Chen Wenzhe has gained some insight.
